FIELD OF THE INVENTION

The present invention relates to a new hybrid tomato (Solanumlycopersicum) variety designated 72-191 RZ.

BACKGROUND OF THE INVENTION

Tomato plants of the species Solanum lycopersicum belong to thenightshade family, also known as Solanaceae. Within this family it isnowadays grouped in the genus Solanum, which does not only harbortomato, but also the important food crops potato and eggplant. It is aperennial, herbaceous, flowering plant species which is native to SouthAmerica.

Other species that are related to tomato within the Solanum genus areSolanum pimpinellifolium, Solanum chilense, Solanum peruvianum andSolanum habrochaites. Although it is known that crossing can beconsiderably difficult, these species are used to obtain traits that arevaluable in growing tomato. In the recent history, advancement in tomatobreeding has lead to tomato varieties having, for example higher yield,higher disease resistance and increased shelf life.

Tomato plants are being cultivated worldwide for their highly nutritiousfruits. The tomato fruit is consumed in various ways, including raw, asan ingredient in many dishes and sauces, and in drinks. While it isbotanically a fruit, it is considered a vegetable for culinary purposes.The fruit is rich in lycopene, which may have beneficial health effects.In 2009, the total acreage for both fresh and processing tomatoes in theUnited States was approximately 442,100 acres, with a total productionof about 14,141,920 tons (source: USDA).

Commercial vegetable production, including the production of tomato, isaffected by many conditions. The choice of the grower for a certainvariety is a determining factor, and forms the genetic basis for theresult that can be attained. In addition, there are many externalfactors that influence the outcome. Growing conditions like climate,soil, and the use of inputs like fertilizer play a major role. There arevarious ways of cultivating tomatoes, among which, the most common are:open field, greenhouse and shade house production. Although the speciescan be grown under a wide range of climatic conditions, it performs mostsuccessfully under dry and warm conditions. In addition to this, thepresence of pests and diseases also affects the total yield that can bereached.

In order to create tomato varieties that are satisfying the needs ofgrowers and/or consumers, many considerations have to be taken intoaccount. The goal is to combine within a single variety or hybrid animproved combination of desirable traits from the parental germplasms.These traits may include higher yield, field performance, fruit andagronomic quality such as firmness, color, content in soluble solids,acidity and viscosity, resistance to diseases and insects, and toleranceto drought and heat. With mechanical harvesting of the tomato fruits forprocessing purpose, i.e., juice, paste, catsup, etc., uniformity ofplant characteristics such as germination, growth rate, maturity, andplant uniformity is also important.

Tomato is a simple diploid species with twelve pairs of chromosomes. Thecultivated tomato is self-fertile and almost exclusivelyself-pollinating. The tomato flowers are hermaphrodites. Tomatocultivars were initially open-pollinated, such as many well-knownheirloom tomatoes, but also varieties were developed for large scalegrowing facilities. Nowadays, especially in a professional growingsetting these cultivars are replaced by better yielding hybrids. Due toits wide dissemination and high value, tomato has been intensively bred.This explains why such a wide array of tomatoes are now available. Thesize may range from small to large, and there are cherry, plum, pear,standard, and beefsteak types. Tomatoes may be grouped by the amount oftime it takes for the plants to mature fruit for harvest; in general thecultivars are considered to be early, midseason or late-maturing.Tomatoes can also be grouped by the plant's growing habit, beingdeterminate or indeterminate. Determinate plants tend to grow theirfoliage first, then set flowers that mature into fruit if pollination issuccessful. All of the fruit tend to ripen on a plant at about the sametime. Indeterminate tomatoes start out by growing some foliage, thencontinue to produce foliage and flowers throughout the growing season.These plants will tend to have tomato fruit in different stages ofmaturity at any given time. More recent developments in tomato breedinghave led to a wider array of fruit color. In addition to the standardred ripe color, tomatoes can be creamy white, lime green, pink, yellow,golden, or orange.

Also breeding for multiple disease and pest resistances is an importantaspect in providing varieties for multiple growing systems and climates.These diseases can be the result of attacks of either nematodes,bacteria, fungi, viruses and/or insects. Important micro-organismscausing such diseases in tomato plants and their fruits in this respectinclude: Meloidogyne incognita (Mi), Verticillium dahliae race 0 (Vd),Fusarium oxysporum f. sp. lycopersici race 0 (ex1) and race 1 (ex2)(Fol), Fusarium oxysporum f. sp. radicis lycopersici (For), Cladosporiumfulvum groups A, B, C, D and E (Ff), Tomato Mosaic Virus (ToMV) strain0, 1 and 2, Stemphylium spp., Tomato Spotted Wilt Virus (TSWV) andOidium neolycopersici (On).

The way in which fruits from tomato plants are harvested is alsorelevant. When the fruits are not ripe at the same time, single harvestof fruits has to be applied in order to provide a fresh product to theconsumer. In the case that fruits of one truss are ripening synchronous,the whole truss can be harvested and be marketed. To support thisdevelopment, the interest for breeding of uniform ripening trusses hasincreased in the recent years.

Oidium neolycopersici is the causal agent of powdery mildew disease intomato. The lack of a sexual stage hampers the exact identification ofthis pathogen, but it is believed to belong to the Ascomycetes. Thefungus causes powdery white lesions on the adaxial tomato leaf surfaceand might also infect other abaxial surfaces, the petioles and thecalyx. The tomato fruit generally remains uninfected. Severe infectionof a tomato plant might result in premature senescence, leaf chlorosisand a marked reduction of the tomato fruit size. (Jones et al. Mol.Plant Pathol. 2(6), 303-309, 2001)

Silvering in tomato, also known as ‘chimera’ is a disorder that is notrelated to a disease caused by bacteria, viruses, insects or acombination thereof. It is called ‘head silvering’ when it affects theleaves that are formed in the shoot apical meristem of tomato plants.This disorder primarily affects tomato that is grown in protectedconditions, especially in northern latitude areas of production. Thewhite or silver color in the tissues of the leaves is caused by largeintracellular spaces which develop through an abnormal formation ofpalisade tissue of the leaf. This happens at a very early stage ofdevelopment. The main factor to positively and negatively influence thisphenomenon is a drastic decrease of temperature, especially at the levelof the shoot apical meristem. Silvering thus affects general plantcondition but might also result in deformed fruits, optionally showinggreenish to yellow streaks (Blancard et al. in Tomato Diseases:Identification, Biology and Control, Manson Publishing, 2012).

DETAILED DESCRIPTION OF THE INVENTION

The invention provides methods and compositions relating to plants,seeds and derivatives of a new hybrid tomato variety herein referred toas hybrid tomato variety 72-191 RZ. 72-191 RZ is a hybrid plant varietythat is uniform and distinct from other such hybrids, and may be stablyproduced after a cycle of reproduction.

There are numerous steps in the development of any novel plant withdesirable characteristics. Selection of traits is a very importantaspect of plant breeding. Once desirable traits are identified, theplants with those desirable traits are crossed in order to recombine thedesirable traits and through selection, varieties or parent lines aredeveloped. The goal is to combine in a single variety or hybrid animproved combination of desirable traits from the parent plant orplants. These important traits may include but are not limited to higheryield, field performance, fruit and agronomic quality such as fruitshape, color and length, resistance to diseases and insects, andtolerance to drought and heat.

Choice of breeding or selection methods depends on the mode of plantreproduction, the heritability of the trait(s) being improved, and thetype of cultivar used commercially (e.g., F1 hybrid cultivar, purelinecultivar, etc.). Popular selection methods commonly include but are notlimited to pedigree selection, modified pedigree selection, massselection, and recurrent selection.

The complexity of inheritance influences choice of the breeding method.Backcross breeding is used to transfer one or a few favorable genescoding for a highly heritable trait into a desirable cultivar. Thisapproach is used extensively for breeding disease-resistant cultivars.Various recurrent selection techniques are used to improvequantitatively inherited traits controlled by numerous genes. The use ofrecurrent selection in self-pollinating crops depends on the ease ofpollination, the frequency of successful hybrids from each pollination,and the number of hybrid offspring from each successful cross.

The development of commercial tomato hybrids relates to the developmentof tomato parental lines, the crossing of these lines, and theevaluation of the crosses. Pedigree breeding and recurrent selectionbreeding methods are used to develop cultivars from breedingpopulations. Breeding programs combine desirable traits from two or morevarieties or various broad-based sources into breeding pools from whichlines are developed by selfing and selection of desired phenotypes. Thenew lines are crossed with other lines and the hybrids from thesecrosses are evaluated to determine which have the desirablecharacteristics.

Pedigree breeding is used commonly for the improvement and developmentof inbred lines of self-pollinating or cross-pollinating crops. Twoparents which possess favorable, complementary traits are crossed toproduce an F1. An F2 population is produced by selfing one or severalF1s or by intercrossing two F1s (sib mating). Selection of the bestindividuals is usually begun in the F2 population; then, beginning inthe F3, generally the best individuals in the best families areselected. Replicated testing of families, or hybrid combinationsinvolving individuals of these families, often follows in the F4generation to improve the effectiveness of selection for traits with lowheritability. At an advanced stage of inbreeding suitable lines are usedas parents to produce F1 hybrids, which are subsequently tested forpotential release as new varieties or cultivars.

Mass and recurrent selections may be used to improve populations ofeither self- or cross-pollinating crops. A genetically variablepopulation of heterozygous individuals is either identified or createdby intercrossing several different parents. The best plants are selectedbased on individual superiority, outstanding progeny, or excellentcombining ability. The selected plants are intercrossed to produce a newpopulation in which further cycles of selection are continued.

Backcross breeding has been used to transfer genes for a simplyinherited, highly heritable trait into a desirable homozygous cultivaror line that is the recurrent parent. The source of the trait to betransferred is called the donor parent. The resulting plant is expectedto have the attributes of the recurrent parent (e.g. the cultivar orparent line) and the desirable trait transferred from the donor parent.After the initial cross, individuals possessing the phenotype of thedonor parent for the preferred trait are selected and repeatedly crossed(backcrossed) to the recurrent parent. The resulting plant is expectedto have the attributes of the recurrent parent (e.g. the cultivar orparent line) and the desirable trait transferred from the donor parent.

Other methods of breeding may also relate to the single-seed descentprocedure which refers to planting a segregating population, harvestinga sample of one seed per plant, and using the one-seed sample to plantthe next generation. When the population has been advanced from the F2to the desired level of inbreeding, the plants from which lines arederived will each trace to different F2 individuals. The number ofplants in a population declines each generation due to failure of someseeds to germinate or some plants to produce at least one seed. As aresult, not all of the F2 plants originally sampled in the populationwill be represented by a progeny when generation advance is completed.

In addition to phenotypic observations, the genotype of a plant may alsobe examined. There are many laboratory-based techniques available forthe analysis, comparison and characterization of plant genotype; thesetechniques include but are not limited to Isozyme Electrophoresis,Restriction Fragment Length Polymorphisms (RFLPs), Randomly AmplifiedPolymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction(AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence CharacterizedAmplified Regions (SCARs), Amplified Fragment Length polymorphisms(AFLPs), Simple Sequence Repeats (SSRs—which are also referred to asMicrosatellites), and Single Nucleotide Polymorphisms (SNPs). Nowadays,sequence-based methods are utilizing SNPs that are randomly distributedacross genomes as a common tool for genotyping (e.g. Elshire et al. PloSOne Vol. 6: e19379, 2011; Poland et al. PloS One Vol. 7: e32253; Truonget al. PloS One Vol. 7 number 5: e37565, 2012).

With any of the aforementioned genotyping techniques, polymorphisms maybe detected when the genotype and/or sequence of the plant of interestis compared to the genotype and/or sequence of one or more referenceplants. As used herein, the genotype and/or sequence of a referenceplant may be derived from, but is not limited to, any one of thefollowing: parental lines, closely related plant varieties or species,complete genome sequence of a related plant variety or species, or thede novo assembled genome sequence of one or more related plant varietiesor species.

Molecular markers, which include markers identified through the use oftechniques such as Isozyme Electrophoresis, RFLPs, RAPDs, AP-PCR, DAF,SCARs, AFLPs, SSRs, and SNPs, may be used in plant breeding. One use ofmolecular markers is Quantitative Trait Loci (QTL) mapping. QTL mappingis the use of markers which are known to be closely linked to allelesthat have measurable effects on a quantitative trait. Selection in thebreeding process is based upon the accumulation of markers linked to thepositive effecting alleles and/or the elimination of the markers linkedto the negative effecting alleles from the plant's genome.

Molecular markers may also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest may be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers may also beused to select toward the genome of the recurrent parent and against themarkers of the donor parent. This procedure attempts to minimize theamount of genome from the donor parent that remains in the selectedplants. It may also be used to reduce the number of crosses back to therecurrent parent needed in a backcrossing program. The use of molecularmarkers in the selection process is often called genetic marker enhancedselection or marker-assisted selection. Molecular markers may also beused to identify and exclude certain sources of germplasm as parentalvarieties or ancestors of a plant by providing a means of trackinggenetic profiles through crosses.

Mutation breeding is another method of introducing new traits intotomato varieties. Mutations that occur spontaneously or are artificiallyinduced may be useful sources of variability for a plant breeder. Thegoal of artificial mutagenesis is to increase the rate of mutation for adesired characteristic. Mutation rates may be increased by manydifferent means including temperature, long-term seed storage, tissueculture conditions, radiation (such as X-rays, Gamma rays, neutrons,Beta radiation, or ultraviolet radiation), chemical mutagens (such asbase analogs like 5-bromo-uracil), antibiotics, alkylating agents (suchas sulfur mustards, nitrogen mustards, epoxides, ethyleneamines,sulfates, sulfonates, sulfones, or lactones), azide, hydroxylamine,nitrous acid or acridines. Once a desired trait is observed throughmutagenesis the trait may then be incorporated into existing germplasmby traditional breeding techniques. Details of mutation breeding may befound in Principles of Cultivar Development by Fehr, MacmillanPublishing Company, 1993.

The production of doubled haploids may also be used for the developmentof homozygous lines in a breeding program. Doubled haploids are producedby the doubling of one set of chromosomes from a heterozygous plant toproduce a completely homozygous individual. For example, see Wan et al.,Theor. Appl. Genet., 77:889-892, 1989

The tomato plant of the invention may be arrived at through crossing ofinbred lines or through selection of the disclosed desirablecharacteristics by any of the breeding and selection methods mentionedabove.

Hybrid tomato variety 74-191 RZ is made from a cross between two uniformparent lines. The male line TS 1446 was internally developed from an F1variety, and selfing and plant selection was done till a stable F8 linewas obtained. The female line TS 1445 was internally developed, from across of two also internally developed lines. The result of a crossbetween lines coded T 271 and T 183 was crossed with T 1421. The resultof this cross was selfed and plant selection was done till a stable F7line was obtained. The female parent line TS 1445 was selected anddeveloped from its initial accession until uniformity on the RZ breedingstation in De Lier in The Netherlands, whereas for the male parent lineTS 1446 a comparable process was performed at the RZ breeding station inAlmeria in Spain. This breeding process, including the cross between TS1445 and TS 1446 was performed to obtain variety 74-191 RZ. In oneembodiment, a plant of the invention has all the morphological andphysiological characteristics of tomato variety 72-191 RZ. Thesecharacteristics of a tomato plant of the invention, e.g. variety 72-191RZ, are summarized in Table 1. In Table 2 the main differences with acomparable publicly available variety are given, when grown under thesame conditions.

The information presented in Tables 1 and 2 was determined in trialexperiments in accordance with official Dutch plant variety registrationauthorities (Naktuinbouw).

The terminology and descriptors used by the Naktuinbouw, and accordinglyin Table 1, are in line with the descriptors of the “UPOV Guidelines forthe Conduct of Tests for Distinctness, Uniformity, and Stability”, orthe “Test Guidelines” for Solanum lycopersicum. The “Test Guidelines”indicate reference varieties for the descriptors or characteristics thatare included in the list. Test guidelines for all crops may be accessedthrough the UPOV website, athttp://www.upov.int/test_guidelines/en/index.jsp.

In an embodiment, the invention relates to a tomato plant that has allthe morphological and physiological characteristics of the invention andhas acquired said characteristics by introduction of the geneticinformation that is responsible for the characteristics from a suitablesource, either by conventional breeding, or genetic modification, inparticular by cisgenesis or transgenesis. Cisgenesis is geneticmodification of plants with a natural gene, coding for an (agricultural)trait, from the crop plant itself or from a sexually compatible donorplant. Transgenesis is genetic modification of a plant with a gene froma non-crossable species or a synthetic gene.

Just as useful traits may be introduced into a hybrid by backcrossingthe trait into one or both parents, useful traits may be introduceddirectly into the plant of the invention, being a plant of hybrid tomatovariety 72-191 RZ, by genetic transformation techniques; and, suchplants of hybrid tomato variety 72-191 RZ that have additional geneticinformation introduced into the genome or that express additional traitsby having the DNA coding therefore introduced into the genome viatransformation techniques, are within the ambit of the invention, aswell as uses of such plants, and the making of such plants.

Genetic transformation may therefore be used to insert a selectedtransgene into the plant of the invention, being a plant of hybridtomato variety 72-191 RZ or may, alternatively, be used for thepreparation of transgenes which may be introduced by backcrossing.Methods for the transformation of plants, including tomato, are wellknown to those of skill in the art.

Vectors used for the transformation of tomato cells are not limited solong as the vector may express an inserted DNA in the cells. Forexample, vectors which may comprise promoters for constitutive geneexpression in tomato cells (e.g., cauliflower mosaic virus 35S promoter)and promoters inducible by exogenous stimuli may be used. Examples ofsuitable vectors include pBI binary vector. The “tomato cell” into whichthe vector is to be introduced includes various forms of tomato cells,such as cultured cell suspensions, protoplasts, leaf sections, andcallus. A vector may be introduced into tomato cells by known methods,such as the polyethylene glycol method, polycation method,electroporation, Agrobacterium-mediated transfer, particle bombardmentand direct DNA uptake by protoplasts. To effect transformation byelectroporation, one may employ either friable tissues, such as asuspension culture of cells or embryogenic callus or alternatively onemay transform immature embryos or other organized tissue directly. Inthis technique, one would partially degrade the cell walls of the chosencells by exposing them to pectin-degrading enzymes (pectolyases) ormechanically wound tissues in a controlled manner.

A particularly efficient method for delivering transforming DNA segmentsto plant cells is microprojectile bombardment. In this method, particlesare coated with nucleic acids and delivered into cells by a propellingforce. Exemplary particles include those which may be comprised oftungsten, platinum, and preferably, gold. For the bombardment, cells insuspension are concentrated on filters or solid culture medium.Alternatively, immature embryos or other target cells may be arranged onsolid culture medium. The cells to be bombarded are positioned at anappropriate distance below the macroprojectile stopping plate. Anillustrative embodiment of a method for delivering DNA into plant cellsby acceleration is the Biolistics Particle Delivery System, which may beused to propel particles coated with DNA or cells through a screen, suchas a stainless steel or Nytex screen, onto a surface covered with targettomato cells. The screen disperses the particles so that they are notdelivered to the recipient cells in large aggregates. It is believedthat a screen intervening between the projectile apparatus and the cellsto be bombarded reduces the size of projectiles aggregate and maycontribute to a higher frequency of transformation by reducing thedamage inflicted on the recipient cells by projectiles that are toolarge. Microprojectile bombardment techniques are widely applicable, andmay be used to transform virtually any plant species, including a plantof tomato variety 72-191 RZ.

Agrobacterium-mediated transfer is another widely applicable system forintroducing gene loci into plant cells. An advantage of the technique isthat DNA may be introduced into whole plant tissues, thereby bypassingthe need for regeneration of an intact plant from a protoplast.Agrobacterium transformation vectors are capable of replication in E.coli as well as Agrobacterium, allowing for convenient manipulations.Moreover, advances in vectors for Agrobacterium-mediated gene transferhave improved the arrangement of genes and restriction sites in thevectors to facilitate the construction of vectors capable of expressingvarious polypeptide coding genes. The vectors have convenientmulti-linker regions flanked by a promoter and a polyadenylation sitefor direct expression of inserted polypeptide coding genes.Additionally, Agrobacterium containing both armed and disarmed Ti genesmay be used for transformation. In those plant strains whereAgrobacterium-mediated transformation is efficient, it is the method ofchoice because of the facile and defined nature of the gene locustransfer. The use of Agrobacterium-mediated plant integrating vectors tointroduce DNA into plant cells, including tomato plant cells, is wellknown in the art (See, e.g., U.S. Pat. Nos. 7,250,560 and 5,563,055).

Transformation of plant protoplasts also may be achieved using methodsbased on calcium phosphate precipitation, polyethylene glycol treatment,electroporation, and combinations of these treatments.

A number of promoters have utility for plant gene expression for anygene of interest including but not limited to selectable markers,scoreable markers, genes for pest tolerance, disease resistance,nutritional enhancements and any other gene of agronomic interest.Examples of constitutive promoters useful for tomato plant geneexpression include, but are not limited to, the cauliflower mosaic virus(CaMV) P-35S promoter, a tandemly duplicated version of the CaMV 35Spromoter, the enhanced 35S promoter (P-e35S), the nopaline synthasepromoter, the octopine synthase promoter, the figwort mosaic virus(P-FMV) promoter (see U.S. Pat. No. 5,378,619), an enhanced version ofthe FMV promoter (P-eFMV) where the promoter sequence of P-FMV isduplicated in tandem, the cauliflower mosaic virus 19S promoter, asugarcane bacilliform virus promoter, a commelina yellow mottle viruspromoter, the promoter for the thylakoid membrane proteins from spinach(psaD, psaF, psaE, PC, FNR, atpC, atpD, cab, rbcS) (see U.S. Pat. No.7,161,061), the CAB-1 promoter from spinach (see U.S. Pat. No.7,663,027), the promoter from maize prolamin seed storage protein (seeU.S. Pat. No. 7,119,255), and other plant DNA virus promoters known toexpress in plant cells. A variety of plant gene promoters that areregulated in response to environmental, hormonal, chemical, and/ordevelopmental signals may be used for expression of an operably linkedgene in plant cells, including promoters regulated by (1) heat, (2)light (e.g., pea rbcS-3A promoter, maize rbcS promoter, or chlorophylla/b-binding protein promoter), (3) hormones, such as abscisic acid, (4)wounding (e.g., wunl, or (5) chemicals such as methyl jasmonate,salicylic acid, or Safener. It may also be advantageous to employorgan-specific promoters.

Exemplary nucleic acids which may be introduced to the tomato variety ofthis invention include, for example, DNA sequences or genes from anotherspecies, or even genes or sequences which originate from or are presentin tomato species, but are incorporated into recipient cells by geneticengineering methods rather than classical reproduction or breedingtechniques. However, the term “exogenous” is also intended to refer togenes that are not normally present in the cell being transformed, orperhaps simply not present in the form, structure, etc., as found in thetransforming DNA segment or gene, or genes which are normally presentand that one desires to express in a manner that differs from thenatural expression pattern, e.g., to over-express. Thus, the term“exogenous” gene or DNA is intended to refer to any gene or DNA segmentthat is introduced into a recipient cell, regardless of whether asimilar gene may already be present in such a cell. The type of DNAincluded in the exogenous DNA may include DNA which is already presentin the plant cell, DNA from another plant, DNA from a differentorganism, or a DNA generated externally, such as a DNA sequencecontaining an antisense message of a gene, or a DNA sequence encoding asynthetic or modified version of a gene.

Many hundreds if not thousands of different genes are known and couldpotentially be introduced into a plant of tomato variety 72-191 RZ.Non-limiting examples of particular genes and corresponding phenotypesone may choose to introduce into a tomato plant include one or moregenes for insect tolerance, pest tolerance such as genes for fungaldisease control, herbicide tolerance, and genes for quality improvementssuch as yield, nutritional enhancements, environmental or stresstolerances, or any desirable changes in plant physiology, growth,development, morphology or plant product(s).

Alternatively, the DNA coding sequences may affect these phenotypes byencoding a non-translatable RNA molecule that causes the targetedinhibition of expression of an endogenous gene, for example viaantisense- or cosuppression-mediated mechanisms. The RNA could also be acatalytic RNA molecule (i.e., a ribozyme) engineered to cleave a desiredendogenous mRNA product. Thus, any gene which produces a protein or mRNAwhich expresses a phenotype or morphology change of interest is usefulfor the practice of the present invention. (See also U.S. Pat. No.7,576,262, “Modified gene-silencing RNA and uses thereof.”)

Such a method may further comprise (c) crossing a plant grownfrom 72-191 RZ-derived tomato seed with itself or with a second tomatoplant to yield additional 72-191 RZ-derived tomato seed, (d) growing theadditional 72-191 RZ-derived tomato seed of step (c) to yield additional72-191 RZ-derived tomato plants, and (e) repeating the crossing andgrowing of steps (c) and (d) for an additional 3-10 generations tofurther generate 72-191 RZ-derived tomato plants. The invention alsoencompasses a 72-191 RZ-derived tomato plant or seed produced by suchmethod.

Backcrossing one of the parents of a hybrid may also be used to improvean inbred plant. Backcrossing transfers a specific desirable trait fromone inbred or non-inbred source to an inbred that lacks that trait. Thismay be accomplished, for example, by first crossing a superior inbred(A) (recurrent parent) to a donor inbred (non-recurrent parent), whichcarries the appropriate locus or loci for the trait in question. Theprogeny of this cross are then mated back to the superior recurrentparent (A) followed by selection in the resultant progeny for thedesired trait to be transferred from the non-recurrent parent. Afterfive or more backcross generations with selection for the desired trait,the progeny are heterozygous for loci controlling the characteristicbeing transferred, but are like the superior parent for most or almostall other loci. The last backcross generation would be selfed to givepure breeding progeny for the trait being transferred.

The invention also encompasses a method of introducing a desired traitinto a plant of hybrid tomato variety 72-191 RZ which may comprise: (a)crossing a parent plant of hybrid tomato variety 72-191 RZ, with asecond tomato plant that may comprise the desired trait to produce F1progeny; (b) selecting an F1 progeny that may comprise the desiredtrait; (c) crossing the selected F1 progeny with said parent plant oftomato variety 72-191 RZ, to produce backcross progeny and (d) selectingbackcross progeny which may comprise the desired trait and thephysiological and morphological characteristics of said parent plant oftomato variety 72-191 RZ, when grown in the same environmentalconditions.
